Results revealed a continuation of the longer-term gradual decline in the proportion using any illicit drug, with 29 percent of college students and 27 percent of all young adults aged 19 to 28 reporting use of a drug in the past year. The use of cocaine and crack also declined. College students had usage rates for marijuana, inhalants, hallucinogens, MDMA, and heroin as noncollege youth and lower rates of use of cocaine, crack, stimulants, barbiturates, and tranquilizers. Forty-three percent of college students reported drinking five or more drinks in a row at least once during the 2 weeks before the survey. However, college students had a daily drinking rate that was slightly lower than that of their age peers, suggesting that they are somewhat more likely to confine their drinking to weekends. College males had higher rates of heavy drinking than did females. Young adults not in college had much higher rates of smoking than did college students.
